This is not quite right. Everyone is calculating the cost of physical ingredients as total economic cost. What about Entrepreneurtia, physical location, staff, overhead, etc. These are all real economic costs. The specific one to concentrate on is entrepreneurtia. Sure, 2 places might make a strawberry lemon vape and charge wildly different prices, but stop and consider what went into those juices. Remeber, for a business owner, mixing up flavors isn't a hobby, but rather a job. Now, shop 1 takes 50% strawberry flavoring and 50% lemon flavoring added to their base, slaps a label on it, and it's ready to go. Entrepreneur A has just spent 20 minutes of his time in production.
Company 2 has a taste stickler for an owner. he tries various ratios, various adjunct flavorings, various steeps until he has produced Bob's magical Strawberry Lemonade. Bob has spent 2 weeks of his life on this (remember this is Bob's enterprise). He doesn't have another job, he rents his mixing building as he wants a truly sanitary lab, among other costs that I won't go into. Now, should entrepreneur A's or B's
juice be more expensive?
This plays to the OP. Many cheap juices are cheap simply because they have Ent. A. Many expensive juices are expensive because they have Ent B. Are there pretenders in the boutique juice market? Of course there are, but many more expensive juices have person B at the helm, and that is who's juice I want to vape.
